Yes, and 10 years after its deprecation, WebSQL is still shipping with Safari and Chrome (worth pointing out that these 2 browsers completely dominate the market).

Interestingly, neither Apple nor Google were pro-deprecation; Mozilla, and to some degree Microsoft, spearheaded the move to standardize on IndexedDB.

Moving forward now that Edge is based on Chrome, maybe there's hope for WebSQL after all. Not that it will be undeprecated, but if 98% of the browser market supports WebSQL then it's effectively a non-standard standard.
